Question

我想在Test :: Say（）中设置一个休息点。中断的方式Test :: Say（）可以做到。但是，rbreak TestSay（）的方法无法做到并报告以下错误信息：

(gdb) rbreak Test::Say()
Can't find member of namespace, class, struct, or union named "main.cpp:'Test::Say()"
Hint: try 'main.cpp:'Test::Say()' or 'main.cpp:'Test::Say()'
(Note leading single quote.)

   class Test
    {
    public:
            Test()
            {
            }

            void Say()
            {
                    printf("Hello word!");
            }
    };


    int main ()
    {
            Test a;
            a.Say();
            getchar();
            return 0;
    }

我建议将gdb升级到最新版本。我用gdb版本7.2重现了你的错误：

然而，最近的gdb版本7.9 rbreak工作正常：

如何正确使用rbreak的命令？
